Possible cause can be design related- if the solder land is too small. Check w/ IPC SM-782 Solder Land Design Guide Another is board finish. I have seen problems like this with Gold finished PWBs- which creates a more brittle solder joint.Another pos

Tin antimony mp = 236-240C 80Au / 20SN mp = 280C sn25 Ag10 sb = 365C There are very few high temperature service alloys. how about filling a 1400lb pot with 80% Gold! What is the application?

CEMCO Uk have done testing using SACX0307, SAC305 and Sn/Cu/Ni. The copper dissolution tests (report available) conducted at CEMCO showed that the lowest copper erosion rate was achieved by SACX0307. Regards Gerry

Any issues in your experience using SAC305 for reflow and SN100C for wave on ENIG pcbs? I've seen the CD, but there's not much specific data regarding ENIG pcbs Thanks
